Yuka Takakura

Tota is struck down while protecting his guardian. Though his wounds should have been fatal, he survives. With his powers awakened,Tota’s life will only get more interesting when he joins a secret society for immortals: UQ Holder.

Koto is a complete and total pervert, but he doesn't think that's a problem. What bothers him is that every time he tries to bluff his way through one of his indiscretions, his inability to drop his emotionless facade inevitably digs him in even deeper.
